Please re-read the documentation. You need to put the jdk14-pluggable-transformer.jar and also the generated jboss-classloader-transformer.jar in your bootclasspath. See section

10.3.2 JBoss 4.x and JDK 1.4

BTW, the reason we did this is because the old way was not reliable as it relied on a JBoss specific classloader. Tomcat and other applications use their own customer classloader in many situations which resulted in things like JSPs not getting aspectized.

BTW, the old EnableTransformer switch still works. So, if you use EnableTransformer instead of EnableLoadtimeWeaving, you can still use the old way.

It works fine for me. Don't worry too much about the contenys of create-pluggable-jboss-classloader.bat. It sounds like it is creating the file as expected

Did you do these steps from the docu:

This will create a jboss-classloader-transformer.jar. Copy this jar to the bin/ directory of your JBoss Application server distribution.

Next, you need to copy the jdk14-pluggable-instrumentor.jar from the lib/ directory of your JBoss AOP distribution to the bin/ directory of your JBoss application server installation. Next edit run.sh or run.bat (depending on what OS you're on) and add the following to the JAVA_OPTS environment variable

Make sure that you add org.jboss.injbossaop to the "Include" attribute of the aspect manager service. Otherwise they get excluded by the org.jboss value put into the Exclude attribute. Entries are comma separated.
